I just tried creating and running my first scratch file in Android Studio and it refuses to execute. Once I "get the red out" of the code, and try to execute it, it invariably gives me this message:

scratch
Error: Could not find or load main class scratch
Process finished with exit code 1
Here's the code (which resides in a file called scratch.java):
public class scratch {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
What am I doing wrong? I'm following the instructions on this video which works fine for him but doesn't work at all for me. Have I failed to install something or turn something on within Android Studio?
I'm running Android Studio 3.1.4 on a Windows 10 laptop.
Scratch file doesn't require to define class or main function, and you can write your code directly in scratch file (file with
.ktsextension)
